Interrupts: help with tests

[darkcoder]

Hello!

I am doing a carefull analisys on clearing interrupt request.
In the end it became an interesting (I think) research on the internal working of 040/060 togehter with Amiga hardware.
To refine my conclusion I would like to have some more test performed.
So please, if you have a 060/040 Amiga, download the following small archive (3K) and perform the test. They will only take you few minutes.
Instructions are in the archive.

thanks to all who will be so kind to help me!

 thank you very much for your interesting results and the very useful scripts!!

I am not comparing which is faster, those are only tests to understand how pipeline and interrupt issues work.
I have one question: is it possible to configure the number of waitstates of BPPC ?? You wrote that in your configuration. Can you give me further details? On which other board it is possible to do so?

regards

I read the page that you have linked in the thread about MOVE16 to know what precharge is. From there I understood it is a delay so I would expect you can configure how long such a delay should be. Instead it is just yes/no ?
How do you perform the configuration? boot-menu?

sorry for so many questions!

  ehehe...

  it could be an idea...indeed I already privately sent the scripts to one betatester who promised me to do the tests but has not yet sent his results.
For now, I had already results with the most common 060/040 boards (namely A3640, Cyberstorm 060 III, BPPC (040), B1260).
Of course other board would be welcome, but the results that I have are sufficient to draw some conclusion...not as interesting as I hoped, but...I am writing a tutorial on interrupts requests for the ADA coding forum.

About the boards, I have a Cyberstorm 060, with a non updated
boot-menu. There is the possibility of setting ram delay (60 or 70ns) but I don't remember this precharge thing. Maybe it's only configurable on the CPPC.

thanks for the info
